Vetere (PSU) report on behalf of the Swift Team:\n\nAt 17:34:33 UT, the Swift Burst Alert Telescope (BAT) triggered and\nlocated GRB 080212 (trigger=303105).  Swift slewed immediately to the burst. \nThe BAT on-board calculated location is \nRA, Dec 231.107, -22.752 which is \n   RA(J2000) = 15h 24m 26s\n   Dec(J2000) = -22d 45' 06\"\nwith an uncertainty of 3 arcmin (radius, 90% containment, including \nsystematic uncertainty).  The BAT light curve showed a single peak\nwith a duration of about 20 sec.  The peak count rate was ~1000 \ncounts/sec (15-350 keV), at ~0 sec after the trigger.  There may be a\nprecursor at T-60 sec. \n\nThe XRT began observing the field at 17:36:19 UT, 106 seconds after the\nBAT trigger. XRT found a bright, fading X-ray source\nlocated at RA, Dec 231.1466, -22.7410 which is\n   RA(J2000)  =  15h 24m 35.1s\n   Dec(J2000) = -22d 44' 27.5\"\nwith an uncertainty of 4.7 arcseconds (radius, 90% containment). \nThis location is 137 arcseconds from the BAT on-board position,\nwithin the BAT error circle. The initial flux in the 2.5s image\nwas 6.9e-09 erg/cm2/s (0.2-10 keV). \n\nUVOT took a finding chart exposure of 400 seconds with the V filter\nstarting 109 seconds after the BAT trigger. No afterglow candidate\nhas been found in the initial data products. There is a object in the\nDSS image inside the XRT error circle which is also detected by UVOT\nwith a magnitude of 17.7. The 2.7'x2.7' sub-image covers 100% of the\nXRT error circle. The 8'x8' region for the list of sources generated\non-board covers 100% of the XRT error circle. No correction has been\nmade for the expected extinction of about 0.5 magnitudes. \n\nBurst Advocate for this burst is H. Ziaeepour (hz AT mssl.ucl.ac.uk). \nPlease contact the BA by email if you require additional information\nregarding Swift followup of this burst. In extremely urgent cases, after\ntrying the Burst Advocate, you can contact the Swift PI by phone (see\nSwift TOO web site for information: http://www.swift.psu.edu/too.html.)",
